1 Be it knownthat I, ROBERT L. GAMnwnLL,

-' a citizen of'the United States of America,

residing at Birmingham, in the county of Jefierson and State of Alabama;ha've invented certain new and useful Improvements in Hollow-TileSilos,- of which. the following is a specification. i

The present invention relates to improvementsin' hollow tile' silos,-and is designed to provide a reinforced structure adapted to'support atank if desired.

- lVhile 'I shall hereinafter refer, in my specification, to a siloconstruction, it will be understood that the invention is equallyapplicablefor use in constructing straight masonry walls for otherpurposes. The primary object of the invention is to reinforce the tileand concrete construction of the-wall so that it will be sufficientlyvention consists essentially. in the combinahereinafter described andclaimed. In'the accompanying drawings tionw-ith the tile or hollowblocks and their concrete cores of specially constructed and.

arranged reinforcing rods or .bars as will be I have illustrated onecomplete example of the physical embodiment of my invention con-'structed according to the best mode I have so far'devised for thepractical application of the principles of my invention, the drawingsshowing a silo structure, but it will be understood that. otherstructures are contemplated within the scope of my invention.

vertical reinforcing rod with itsi ends air gaging horizontalreinforcing rods or bars choring roof rafters when tank is omitted:

In the preferred embodiment of myiri'n vention as shown in the drawingsthetsil wall is made up of courses of tiles orxhol low blocks as 1, laidcourse upon course'gant the. blocks are molded with inner and folltei tfcurved faces to provide a circular; wallwhen the. rows are completed.Each r-block' is formed with an outer vertical web 2, a par-.3...

tition or intermediate web 3 and itsinnerh weh, while the end webs 5, 5,complete the outline of the block.

curved to form a semi-cylindricalspace 10 and the curvedintermediatepartitions l1 which extend transversely between the concreteas indicated in the drawings"the cores of concrete extending from thebot-fl tom to the top of the structure and fil'liilg wall are reinforcedby .a' continuous'netf work of metal bars or rods WI h extend's 1 aroundthe silo andare' util; ed hold-the blocks in vertical ali-nementfl omthe bottom to the 'top of the silo.

The reinforcing net work comprises a series of horizontally extendingbars as 13 each of which extends from one door jamb provided withgrooves or notches in their;

These notches are located at the top of the blocks just to one side oftheir center lines. and extend through the end walls, the longitudinalintermediate walls and the curved intermediate partitions 11, so thatthe-curved bars 13 may be laid on the top of each course of hollowblocks, resting in the grooves or notches. horizontal bars, in pairs,are a multiplicit of vertically extending rods 16 formed wit 1 end hooks17 opening in opposite directions as seen in Fig. 10. These hooks areadapted to engage over the horizontal bars, and the rods pass throughthe voids or spaces extending vertically through the blocks, a

which it will of course be understood are open at top andbottom. InFigs. 7 and 10 it will be seen that the upper hook 17 engages over the.upper horizontal bar and it These webs provide' the four spacesfi, 7, 8,9, the end Walls. are

75 two side walls 2, 4t formcylindrical-spacey; 12. In use all thesespaces are filledlwith'."

so the crevices between the blocks- 'of'each course and row. These.blocks forming" the 9O 14 to the other jamb 14- and the blocks 1 are IfConnecting these doorway, but connecting The arrangement of the hooksand that the lower hook engages under the lower bai. rods on the bars iswell shown in Fig. 7 a where it will be seen that an effective net workof reinforced metal is provided which permeates the silo wall from topto bottom and throughout its circular wall.

In Fig. 5 a hook 13. is shown at the end the horizontal ring or bar 13which hook engages about the rod 16 in the half jamb block 18, and theother end of the bar (not shown) is hooked to a similar rod 16 acrossthe doorway. The bars 13 stop short of the bars 19, (Figs. 1

and 2) extend across the doorway from jamb to jamb in line withthe bars13 and these connecting bars have hooks 19 engaged about the verticalrods 16. These connecting bars, in addition to strengthening and bracingthe door way, perform the function of ladder rungs or rounds so thatascent of the silo may be accomplished at the doorway extending frombottom to top of the silo.

The doorway is closed by door sections 20 which are supported on theprojections 21 of the sills '22 and the sills are blocks spaced way fromjamb to apart vertically, extending across the doorj amb with ahorizontally extending bar 19" therethrough for reinlforcement. Thedoors are preferably lined with asbestos paper to make the joints airtight, and at the ends have rounded edges 23 which fit neatly into therounded or grooved corners 24 of the'jambs at the inner side of thedoorway. I

When the tank is supported at the top of the silo as indicated at 25 inFig. 8 the wooden joist 26 beneath the tank bottdm 2'7 is secured to thesilo wall by means of the angle bracket 28 which is nailed to the ,joistand has an anchoring rod 29 fixed therein and passed through the woodplate 30 into and is embedded in the concrete core of the block 1.. When a sloping or peaked roof is used instead of the tank at the top ofthe silo, the rafter 81 is supported by the bracket and anchoring rod asshown in Fig. 8.

It will be understood that all the circular voids or spaces in' theblocks are filled with concrete, and these concrete'cores together withthe interior net work of reinforcing steel bars and rods, render thestructure exception-ally strong and capable of bearing great weight. Itshould be noted that the websof the blocks in courses, have a perfectbearing upon tlie'webs below, as the horizontal bars are embedded belowthe top surface of the blocks.

I claim A wall composed of hollow blocks laid in courses and formed withlongitudinal grooves having a horizontally extending 'bar in the groovesof each course below the top thereof, said blocks each fashioned withcurved end walls tornnng vertical spaces between ad oining blocks and anlntermediate space in each block, vertically ar-.

ranged rods passing through said spaces and hooked ends on said rodsengaging said horizontal bars in pairs, and concrete cores incasing saidrods and embedded in the spaces of the blocks.

In testimony whereof I afiix my signature.
